In the theater world, there’s that magical phenomenon known as the “showmance” — a love affair that sparks when two people meet in a stage production.

Of course, not all of those romances last beyond the actual run of the show. So hats off (and rings on) to the five married theater couples — or nearly so, in one case — who will take the stage Friday for “Kiss&Tell,” a special Valentine’s cabaret event from Moonlight Stage Productions.

The idea was the brainstorm of Moonlight managing director Colleen Kollar Smith, who happens to be married to the actor-playwright Lance Arthur Smith and will perform with him in the show.

“One of the questions we get more often than not is, ‘How do you do this — how do you have a family and do theater?,’” says Kollar Smith, who’s also an actor-choreographer and the mom of two young daughters.

“But you know what? There are so many of us who do it. So let’s get some of those folks together to talk about what it is to love in the business of theater.”

“My request to them was, pick songs that lend themselves to sharing a little insight to what your story is in theater,” Kollar Smith says. (The tune she and her husband are performing together, “It Only Takes a Moment” from “Hello, Dolly,” is a nod to the Lamb’s Players Theatre production of that show the pair acted in while they were expecting their first child.)

There was a logistical challenge or two: Geno Carr is appearing on Broadway in the La Jolla Playhouse-launched musical “Come From Away” right now, so he’ll perform with the assistance of video technology; same for Malone, who’s out of town with “Honky Tonk Laundry.”

Some of the performers also will play instruments, complemented by music director Elan McMahan, who’ll play piano on the stage of the heated, indoor ClubM cabaret venue. (The venue offers table seating; food and drinks will be available for purchase.)

So, there will be romance — but what about romantic drama?

Sorry, not on the program.

Kollar Smith says with a laugh that she has one job above all others: “Keep everybody in harmony.”
